Question

This is probably a very simple question but I just can’t seem to figure it out.

I am writing a Javascript app to retrieve layer information from a WFS server using a GetCapabilities request using GeoExt. GetCapabilities returns information about the WFS server — the server’s name, who runs it, etc., in addition to information on the data layers it has on offer.

My basic code looks like this:

var store = new GeoExt.data.WFSCapabilitiesStore({ url: serverURL });

store.on('load', successFunction);
store.on('exception', failureFunction);
store.load();

This works as expected, and when the loading completes, successFunction is called.

successFunction looks like this:

successFunction = function(dataProxy, records, options) { 
   doSomeStuff();
}

dataProxy is a Ext.data.DataProxy object, records is a list of records, one for each layer on the WFS server, and options is empty.

And here is where I’m stuck: In this function, I can get access to all the layer information regarding data offered by the server. But I also want to extract the server information that is contained in the XML fetched during the store.load() (see below). But I can’t figure out how to get it out of the dataProxy object, where I’m sure it must be squirreled away.

Any ideas?

Apparently,GeoExt currently discards the server information, undermining the entire premise of my question.

Here is a code snippet that can be used to tell GeoExt to grab it. I did not write this code, but have tested it, and found it works well for me:
